Saw him train at Worlds Venice (Main St & Abbott Kinney) a few times in 92'- 93'... I think. That would have been post Terminator II. All upper body stuff; dumbell presses, seated side laterals, upright rows... some bicep & triceps work. Nothing crazy. He was training with Ralph Muller a bit at the time.
In all the years at Gold's Venice, I only saw him in that gym one time. He wasn't there to train, he was just giving some friends a mini-tour.
I have seen him at Sparky's Yougurt about 50 times though.... does that count?
